Pre-cal week 18

through out this past semester of pre calc 11 I’ve learned a lot of new ways of math, the one I would like to show you that has now stuck with me is how to determine non-permissible values from rational expressions.

In this question, you first start by taking out the denominator. With this denominator factor it to find the x values. The denominator can never equal zero. By finding finding the x’s you are finding the non-permissible values.

 

Blackout Poem – “Death of a Salesman”

“Death of a Salesmen” Written by Arthur Miller, the play was given a theme of tragedy throughout the play. “Death of a Salesmen” is a play about a 63 year old salesman named Willy Loman, who is showing early signs of Alzheimer’s. Which one would see that it is leading him towards the lack of progress within the sales industry and damaging relationship though out the family, mostly the sons. Willy wants to live the American Dream like his father who was a very successful salesman that made flutes and sold them. Willy has never been able to do so, due to this, he becomes very angry with his oldest son Biff and takes about become successful in life.

The play falls in the genre of tragedy because it shows Willy Loman who could become successful in his life, but with the bad choices made due to his illness, he loses a lot and can not gain them back. The relationship with his sons when they were younger compared to now will never be the same, from the way Willy acts towards them now. He puts so much pressure on them to become successful. One would see that Willy is a hard-working person who is more than capable of becoming success but gets distracted over his looking for a belonging that are tangible which shows examples of the theme tragedy though out the play.

The project for this play was to create a blackout poem, where one finds words in a piece of literature that could make a poem or just words that describe the play, doing this by colouring out the other words in the piece of literature found. One will see that in the piece of literature bellow that words were chosen to describe the play. Not a man to trust, no good as a father and though his love, these words chosen relate to Willy. Not a man to trust, is shown through out the play because Willy has a mistress that Linda, Willy’s wife does not know about and has flashbacks off her when he would work in Boston. No good as a father, Willy was not a good father towards Biff and Happy and does not accept anything they do and only wants them to become successful, but he never listens to them. Through his love, at the end of the play Biff tells Willy he loves him after they get into an argument and Biff leaves. Willy has never heard Biff say that to him and gets ecstatic with the fact and keeps repeating it, while Happy and Linda say he has always loved you. Willy being overwhelmed with joy and happiness gets into his car and kill him self so their family can get money and live without asking people for help to pay rent on the house.

In the end, the play tells us that you don’t need everything to be happy and when trying to do so you can develop bad relationships with others and make bad life decisions.

Constructive and destructive interference waves

Destructive interference: a crest and trough meet ( the waves are “out of phase “), the energies combine to work against each other – they tend to cancel out

Constructive interference: when a crest from one source meets a crest from another source, the energies combine to displace the medium ( the energies are additive )

Standing waves : when interferencing waves have the same amplitude and wave length l, resulting interference pattern remains nearly stationary and is called as standing wave interference pattern ; a node or nodel points is a point that remains at rest throughout the interference of the pulses

DOAS Monologues

The following is an example I created of a monologue for the character of Biff from “ Dealth of a Salesman”.

This is a monologue because Biff is talking while other characters are there but he is uninterrupted and reveals a lot about the character.

This monologue would fit in the current plot when biff is talking to happy about going to getting a better job here.

Biff: Hap, Hap, listen to this we open up a bro store. Me and you working together, we can help support Mom and Dad together. We, we could become millionaires together Hap, doesn’t that sound fun. Us working together just like we were young and fighting the world together, now we can own a busy and become rich. I came home for a reason Hap, you think the horse would make me money, I want money Hap lots and lots of it. Why don’t you give it a thought Hap and tell me what u think about us the dynamic duo working together, making money left right and centre?. Just imagine if we made so much money we wouldn’t need to work and we could have slaves and still make loads of money, and don’t, don’t even get me started on our pension we wouldn’t need to worry Hap.

Pre- cal Week 17

One thing I learned this week in Pre Calc 11 is how to find the side of a triangle using Cosine Law. The Cosine Law is used when you need to find a third side of a triangle. Tip: When trying to find a third angle of a triangle use the Alternate Cosine Law.

A trick to knowing when you are going to be using the Cosine Law is when you see a question asking to find the measurement of the third side of the triangle, and they give you the other two sides of the triangle and the angle between them.

Below is an example of a triangle where you need to find the third side. I will show how I determine what formula to use and how to solve…

Pre-Cal, Week 13

I learned this week in Pre Calc 11 is how to write absolute value functions in piecewise notation. We already have learned about absolute values (reference back to week 3 blog post for reminder). This week we learned about piecewise notation, and how to understand and write it for a absolute value function.

Piecewise notation is used to describe a function that has different definitions for different parts of the graph. When writing absolute values we use piecewise notation to describe the absolute value of the number.

In the example below follow the steps I take to write a absolute value function in piecewise notation…
